org.codehaus.jackson.map.deser.SettableBeanProperty

org.codehaus.jackson.map.deser.impl.CreatorProperty

所有已实现的接口:

BeanProperty, Named

public class CreatorProperty
extends SettableBeanProperty

This concrete sub-class implements property that is passed via Creator (constructor or static factory method). It is not a full-featured implementation in that its set method should never be called -- instead, value must separately passed.

Note on injectable values (1.9): unlike with other mutators, where deserializer and injecting are separate, here we deal the two as related things. This is necessary to add proper priority, as well as to simplify coordination.

Note that this class was moved in Jackson 1.9 from being a static sub-class of "org.codehaus.jackson.map.deser.SettableBeanProperty" into separate class, to make it easier to use it for custom creators.

_annotated

protected final AnnotatedParameter _annotated

Placeholder that represents constructor parameter, when it is created from actual constructor. May be null when a synthetic instance is created.

_injectableValueId

protected final Object _injectableValueId

Id of value to inject, if value injection should be used for this parameter (in addition to, or instead of, regular deserialization).

构造器详细资料

CreatorProperty

public CreatorProperty(String name,
               JavaType type,
               TypeDeserializer typeDeser,
               Annotations contextAnnotations,
               AnnotatedParameter param,
               int index,
               Object injectableValueId)

参数:

name - Name of the logical property

type - Type of the property, used to find deserializer

typeDeser - Type deserializer to use for handling polymorphic type information, if one is needed

contextAnnotations - Contextual annotations (usually by class that declares creator [constructor, factory method] that includes this property)

param - Representation of property, constructor or factory method parameter; used for accessing annotations of the property

CreatorProperty

protected CreatorProperty(CreatorProperty src,
               JsonDeserializer<Object> deser)

findInjectableValue

public Object findInjectableValue(DeserializationContext context,
                         Object beanInstance)
